COMBINATION AUTO LOCK.

A 'iplication filed March 16, 1920. Serial No. 366,350.

To all whom it may concern:

Be 1t known thatLTnoMAs HUDSON, a citizen ofthe United States, residing at Los Angeles,.in the county of Los Angeles and State of California, have invented-new and useful Improvements in Combination Auto Locks, :of which the following is a specification. 1 l

This invention relates to combination locks and switches andhas' for its objectto provide an improved combination lock switch for automobiles, and further has for its object to provide a device that is not only extremely simple but is substantial and reliable and provides for the effective interruption of electric circuits of an automobile organization so as to prevent the starting of the engine until the combination lock. has been properly set so as to secure the closing The invention consists of the construction, the combination and in details and arrangements of the parts, an embodiment of which invention is illustrated in the accompanying drawings and described and claimed herein.

Figure l is a front elevation of the improvedlock shown as mounted on the dash board of an automobile.

Fig. 2 is a central diametrical section through the improved device.

Fig. 3 is a section on line 3-8 of Fig. 2.

Fig. 4 is a section on line 44 of 2.

Fig. 5 is a section on line 5-5 of Fig. 2.

The present combination lock switch comprises a shell or casing 2 having an outturned flange 3 at the open end of the shell which has a back or closed end 4. The flange may be countersunk in the usual instrument board B of an automobile in relation to which automobile the switch is introduced into any, or as many, of the electric circuits as may he desired as, for instance, into the ignition circuit and in the starting circuit so that so long as the switch is closed the circuits are complete, but when the switch is open the circuits are broken and cannot be again closed until the circuit closing members of the switch are brought into contact by the proper manipulation of the combination elements of the lock.

The lock is provided with a face plate 5 that may be screwed or otherwise secured as at 6 to the instrument board B and this plate covers themouth of the box or shell 4:. On the front of the. plate is a concentric index wheel 7 fastened as by means of a screw 8 to the hub 9 of a driving tumbler or disc 10 having its hub portion journaled in an aperture providedtherefor in the center of the plate 5. Through. the hub of the driving disc IO'eXtends a spindle 11 having secured on its outer end beyond the combination wheel 7 an operating. lever 12. The combination disc 10 has a peripheral portion 10 in the form of a flange in which there is an annular groove 10*, and arranged in this groove there is a radial shoulder or pin 13, Fig. 5, which when turnedby the rotation of the spindle 11 is designed to engage a complementary pin or shoulder 14 that is provided in the outer and concentric tumbler or annulus 15 turnably fitting on the flange 10 of the tumbler 10. Y

The outer tumbler 15has a radial notch 15 and the inner tumbler has a radialnotch lO" and these notches are designed to be brought into radial registration by the manipulation of the combination wheel 7 to which the driving tumbler is secured; first by setting the outer tumbler 15 with its notch 15 and then by turning the inner tumbler 10 to bring its notch l0 adjacent to the notch 15'.

When the notches have been co-ordinated the handle 12 with the spindle 11 can then be drawn outwardly so as to bring a radial pin ll on the spindle 11 into the registered notches 10 and 15. This brings the circuit closing members 16, secured as by screws 17 on the inner end of the spindle 11, into juxtaposition to fixed contact fingers 18, and then by rotating the handle 12 and the spindle 11 the contact blades 16 are brought into frictional engagement with respective contact fingers 18 and the circuit completed.

The fingers 18 are shown as mounted on and insulated from a rearwardly extending hearing 20 through which the spindle 11 projects inwardly, and this bearing 20 is provided with an annular chamber 21 in. which the spindle pin 11? may freely rotate when it has been projected inwardly out of interlock with the tumbler notches 10* and 15' and at which time the circuit closing blades or plates 16 are disalined from the respective contact fingers 18. The bearing part 20 has its front portion turned to make a running bearing or fit for the periphery of the outer tumbler 15 and also has an outwardly'extending flange 22 to receive fastening screws 23 passing through the face plate 5.

From the above it will be seen that the controlling circuits ofa starting plant and of the ignition system of an automobile can be interrupted by thedisconnection of suitable switches including members that are mounted on the spindle of the combination lock and which will serve to hold the brushes out of'circuit closing position until the combination tumblers of the lock have been properly set to permit the forward movement of the spindle to bring the brushes'or blades into proper alinement with complementary contact members of the circuit and after which the brushes or blades can be turned into electrical contact to complete the circuits; 7

Various changes may be made without departing from the spirit of the invention as claimed.

What is claimed is:

1. A combination lock switch comprising fixed contacts, a rotatably mounted combination disc having a combination element attached thereto, a second combination element journaled upon and movable by the first named combination element, said elements having slots adapted tobe alined said combination disk and combination element being provided with shoulders that are adapted to engage so as to bring the slots in said members into alinement with each other, a splndle rotatably arranged wlthin sald combination disk and having a radial acey/cc the housing, a member fixed to said disk and provided with an annular groove in which is formed a shoulder, amember arranged -ior rotation on saidgroovedflange and pro vided with a pin that is adapted to enter the groove in said flange and engage the shoulder therein, said rotatably mounted member and flange being provided with apertures that are adapted to coincide when the pin is in engagement with said shoulder, a spindle mounted for rotary movement and for axial movement-through said combination disk, a radial pin carried by said spindle and adapted to occupy the alined slots, contact members carried by said spindle andadapted to engage with the fixed contacts, and a handle secured to the forward end of said spindle for actuating the THOMAS E.
